Abstract

The invention relates to the technical field of medical appliances, and discloses a basis cranii repairing device for resection of pituitary adenoma via sphenoid sinus. The device comprises a first plug disc and a lumbar support formed on the first side of the first plug disc, wherein the first plug disc and the lumbar support have metal reticular structures; the second side surface of the first plug disc is coated with a first flexible blocking layer; the first flexible blocking layer is larger than the first plug disc, and the periphery of the first flexible blocking layer extends out of the edge of the first plug disc. The basis cranii repairing device can be used for effectively repairing the skull defect after repairing operation due to the first plug disc and the first flexible blocking layer, cerebrospinal fluid leakage is prevented, and infection rate is reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a skull base repair device for transsphenoidal pituitary adenoma surgery. Background technique [0002] Pituitary adenoma is currently the second most common intracranial tumor, and transsphenoidal minimally invasive surgery is the first choice. Cerebrospinal fluid leakage due to postoperative skull base bone defect is the most common complication of this operation, which can lead to intracranial infection, threaten the life of the patient, and restrict the curative effect of the operation. At present, meningeal patches or nasal mucosal flaps are usually used clinically after surgery to repair the skull base defect caused by surgery to prevent postoperative cerebrospinal fluid leakage. The repair effect of meningeal patch is not good, and the lack of effective physical support often leads to repair failure, requiring a second operation for re-repair, which increases the ...
